Presto Vivace writes H-1B records that are critical to research and take up a small amount of storage are set for deletion. "In a notice posted last week, the U.S. Department of Labor said that records used for labor certification, whether in paper or electronic, 'are temporary records and subject to destruction' after five years, under a new policy. There was no explanation for the change, and it is perplexing to researchers. The records under threat are called Labor Condition Applications (LCA), which identify the H-1B employer, worksite, the prevailing wage, and the wage paid to the worker. The cost of storage can't be an issue for the government's $80 billion IT budget: A full year's worth of LCA data is less than 1GB."
